Expose initializer with optional parameters in generated Swift code

[tbogosia]

In version 9.1.0 of Typewriter, it looks like a convenience is generated to create a tracking event with optional values:

    func with(
        parameter1: String?? = nil,
        parameter2: String?? = nil
    ) -> MyEvent {
        return MyEvent(
            parameter1: parameter1 ?? self. parameter2,
            parameter2: parameter2 ?? self. parameter2
        )
    }

It would be great to have something like this, but more of a static function with default values for optional properties, like:

    static func with(
        parameter1: String? = nil,
        parameter2: String? = nil
    ) -> MyEvent {
        return MyEvent(
            parameter1: parameter1,
            parameter2: parameter2
        )
    }

This way at the call site I could use MyEvent.with(parameter1: "value") rather than need to pass in nil for all of the properties I know aren't relevant. I could see a case made for wanting to bring attention to all properties at the call site, but at least in my app this would save a lot of unnecessary noise.
